Combo-Scope

The manufacturer of this great little device, C&A Scientific Company Inc., calls this a Spy Scope, but we think its multiple optical applications in one very small package are the story here. The very cool 8 X 20 spotting scope has an adjustable focal length from 1" to infinity. It measures a mere 4-7/8" long when extended, with a rubber grip and eyepiece cover and wrist strap. And it comes with a 3-1/4" tall 5X loupe that's threaded to mate with the scope to create a 25X microscope. The plastic microscope stand/extender is also threaded and will come apart from the loupe. Comes with a black nylon belt pouch for the spotting scope. Can you say "multi-task?"

Field & Forest Guide

Titled "The Field and Forest Handy Book," this volume has been justifiably in print since 1906. Written by Daniel C. "Uncle Dan" Beard, the founder of the Sons of Daniel Boone and one of the founders of the BSA, it's a compendium of eternally relevant woodland lore, from building cabins, sleds, boats, and bridges to camping in swamps. The only part we skipped was on how to cook a muskrat. (We know a place that delivers.) Loaded with illustrations. In soft cover from David Godine's Nonpareil Books, 428 pages.

Electric Styro Knife

"Screeeeeek! Screeeeeek! Screeeeeek!" Recognize that? It's the sound of someone sawing a styro-foamal block. It's followed by the sound of a vacuum sucking up hundreds of little foam shards. Free yourself from both with this clever electric hot-knife that slides through those chunks of craft foam like a straight razor through a ripe mango. Perfect for carving foam blocks into shapes - or smaller blocks. Measures 10" long OA with a 4-3/4" long, needle-like cutting wand, heats up to 410°F (so be careful), and makes screeeek-free and shardless cuts. Has a 7-foot cord, line switch, safety stand, and wall-outlet adapter.
